A tease of whats to come in the near future! An MTF collab microbe blend at my lab Mainiacal Yeast! This will be a pretty rugged blend in terms of temperature tolerance. It'll include 4 Kveik cultures and 2 Lactobacillus plantarum. It has a crazy temperature range of 60-105F. The higher the temp the quicker the turn around and more expressive the Kveik will be. In our trials of this its been straight sour pineapple juice at higher temps. The turn around for both souring and fermenting was 4 days. It was in the glass on the 5th day. This was at 95F. If fermenting colder you can expect a longer fermentation time upwards of 1-2 weeks on the lowest side. You'll also have a bit of a clean fermentation at lower temps. For those who don't have temp controls to increase the heat you can just rack out of the kettle around 105F or less, pitch and let it free fall.
In trials where we didn't drop the pH the pH dropped to 3.4 in those 4 days, the FG was 1.010 as well. In trials where we preacidified to 4.5 pH and pitched the culture we got down to a 3.2 pH in 3 days and a gravity of 1.009 in 4 days.
The Lacto in this blend is very intolerant of hops so if you plan to use any and want any souring I'd suggest dry hopping post souring.
The blends ratio will have 150 billion cells of Lacto and 75 billion of Kveik. Allowing the Lacto an advantage before the Kveik rips through it. This blend will also continue to sour a bit more if left to age and is also a great blend to chuck a Brett strain in post ferment/souring for a longer aged more complex sour. The Kveik tend to have little to no issues in lower cell counts. I would however suggest adding some yeast nutrient if you are planning to ferment 85F or above as Kveik tend to be a little more demanding at higher temps.
We are starting this blend in a couple tanks Friday and will update once we have a release date.
This blend is a thanks to MTF and MTF community for all the hard work done on both the research and recording of all of this data! Thanks all!
